WHEELWRIGHTS MACHINE.

Specification of Letters Patent No. 32,277, dated May 14, 1861.

To all whom t may concern:

Be it known that I, N. Tl EDsoN, of New Orleans, paris of Orleans, andState of Louisiana, have invented certain new and useful Improvements inMachines for Making Carriage-Iheels; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebe-` ing had to the accompanying drawings, forming part of thisspecification, in which- Figure l lis a perspective View of my machinewith a hub (composed of two metallic.u

lanches box and nut) and two spokes placed therein.

Fig. 2 and Fig. 5represent the inner or lower surface of the flanch 2Fig. l, the projections D.D. D. entering corresponding grooves formedin` the spokes, by which means the spokes on being driven with a lightpressure upon the ring and flanch by turning the screws A. A. A. areforced one against the other and held in their respective positions inthe hub and also admit of a spoke being removed and replaced withoutdisplacing the whole.

Fig. 3 is also an 4inside View of flanches with projections whichcorrespond with the size and form of the tenon of the spokes and whichprojections, are divided by groovespf the same form, two of whichflanches are used to form a hub with the grooves of one flanch oppositeto the proj ections of the other, by the use of which flanches, wheelsof dogged spokes are made.

A. A. A. in Fig. l are screws which pass through the headpiece 1 as seenat l. l. l. by which the ring 5 is forced down upon the upper flanch 2with an equal pressure on all parts. B. is a bolt passing through thehead piece l box E. base G. and terminating with a nut or head on itslower end. C. is a nut which screws down to the head piece 1 on the boltB. to hold the headpiece while the screws are being turned down on thering 5 and t-he nut D. screwed down to the anch 2. D is a nut screwedupon box E. which rests upon and holds the flanch 2 down upon the spokesH. H. after the fianch has been pressed sufficiently hard with thescrewsA. A. A. F. F. are guides attached to the base G. and which togetherwith the pins J.

and knees K. hold the spokes straight with each other on the anch 3. 4is a rim resting on the four arms of the base Gr..which holds the spokesto a proper elevation for the dish of the wheel. L. L. L. L. are thefeet or supports of the machine.

Fig. 4 lis a tube to be placed on the base G. to receive the pressure ofthe lower fianch 3, as that flanch without such support is liable to bebroken when the spokes are being pressed. A. A. A. Fig. 4 are set screwsto press against the box to prevent its turning in the hub while the nutD. is being screwed down if the wheels are to be used in a cold climatethe box E. should be made of malleable iron or steel and with bothfianches movable or separate from the box.

In the use of my machine in making the ordinary wood hub wheels the tubeFig. 4 isn dispensed with the headpiece with its screws and the ring 5may. in most instances also be dispensed with and the nut C. turneddirectly down on the hub to hold it true with the rim 4 while all thespokes are being driven and the felly or rim of the wheel being put on.l

Having thus described my invention what I claim therein as new anddesire to secure by Letters Patent is The combination of the form orstand L.
